There's a picture of the truth. Search engine Identification keyword approach analysis

What is a keyword? As with paper writing, the site's keywords are the subject of a site, or the content of a site's core location. It can even be understood that the content of the site revolves around a center, content and what is relevant. For example, website construction as the main content of the site, you can be identified as "website construction", "website production", and so on, but not "packaging design", although the two have a certain correlation. Unless like Sina, Sohu such comprehensive portal site, the content is not inferior, so can not be specific to a certain keyword (in fact, similar to Sina, Sohu, such as the portal site, each different channel has different keywords). The vast majority of sites should be the main body, especially small and medium-sized sites. So many websites, how does the engine identify keywords? For example, we search the word "Shanghai website construction" This keyword, the search engine how to know which website is more in line with user experience, is the website that the visitor wants to look for? After in-depth analysis, we believe that the search engine to identify the key words of the way, no less than the following three kinds:

　　Meta-META tags

As long as you carefully think about site optimization, you should know the importance of meta tags. Meta tags are actually prepared for search engines because, for example, keywords and description, unprofessional users will not notice, but not on the page. The main purpose of META tags is to facilitate the search engine cognitive sites, so that the content can be categorized into the corresponding search directory. But this does not mean that meta how to write a search engine on how to collect. In fact, search engines in the classification of the content of the site, they will have a process of comparison. But the statements in the META tags will have a certain priority, that is, if the content of the meta is in line with the theme of the site, will be preferred to be included, otherwise the search engine will crawl from the page a more appropriate content, and give up meta inside the existing statements.

　　

　　

Knowing this, we can at least be aware of the two-point content. First, meta is very important, is the search engine to determine the theme of the main source of information, whether the site title or keyword, or content description can not be lightly. Need to pay attention to, especially the site title and page content description, can be indexed by search engines, directly related to the image of the site. The second can be perceived is that meta can not be arbitrary to write, must match the content of the site, to meet the site theme. As long as this is the case, meta information content can be used by search engines. There is no doubt that the meta inside should be reasonable layout keywords, to effectively convey the site to the search engine theme and user-friendly identification.

　　Second, the keyword layout

Whatever meta describes, the content is ultimately fundamental. In the actual search engine included performance, there are a lot of direct jump Meta, directly included and the content of the page to take place. Therefore, the effective in the content of the page, reasonable layout and display keywords, you can increase the number of sites related to the ranking of keywords. Effective keyword layout has two ways, and are relatively mature, search engines are also very recognized. The two approaches are keyword density, and special label tagging. Keyword density is easy to understand, that is, in the page content, reasonable to improve the density of keywords. But the promotion of keyword density, must be built on the basis of reasonable fluency, not malicious piling up keywords.

　　

　　

Key words will be highlighted, so that search engines and users can easily identify, but also a very effective way to layout keywords. And it turns out that the effect of this implementation is even more desirable than the enhancement of keyword density. Keyword special tagging methods are generally: through <b> or <strong> tags will be bold, or through the <font> tag to increase the font size, or give a distinctive font color or color, and intentionally in the keyword below through <u > Label underline and so on. Keyword key signs of the advantage is not subject to the keyword density size, in the assurance of clear logic of the content of the statement, on the basis of the search engine and visitors to quickly identify.

Third, the anchor cable Connection text

Massive backlinks, not only can improve the overall weight of the site, the same can make search engines faster and better identify the site keyword. We know whether the chain or outside the chain, links are divided into two ways, one is only the link to the URL, there is an anchor text link. The anchor text link is more for the purpose of delivering the site to the search engine theme and keywords. For example, in the implementation of links inside the link, we can some of the content of the page, some of the keywords, the absolute path to connect to the corresponding page. This on the one hand to facilitate the user to find relevant content, but also perfect implementation of the station optimization. If you can make the keyword bold, and then in the anchor text link, the effect will be better.

　　

　　

　　

In fact, our friendship link exchange, is a simple and practical anchor text link outside the station. Generally speaking, the anchor text that comes from outside the station reverse link, the effect is much better. But the friendship link has the quantity limit after all, must pay attention to the link resources quality, the friendship link also must be in line with the Ningquewulan principle, because the search engine has the same "birds of a feather flock together" the snobbish viewpoint, wants to do the quality website naturally to and the higher quality website link. Anchor text links are not just meta and keyword layout of a useful supplement, it can not only make the search engine easier to identify site keywords, but also to bring weight to the site.

No matter which way the search engine identifies the keyword, the theme of the website or the theme of a particular channel, it is in fact unified and determined. In other words, for a Web site, its meta tags, content-enhanced keywords and anchor text, should be "four-digit word" highly unified. Professional website Construction company Pilotage Technology (www.joyweb.net.cn) Point of view is that, since the emphasis on the keyword "four-bit", then its determination and layout is a very systematic project, especially the anchor text links outside the station, once the beginning of many is no way to modify the adjustment. Website construction and website optimization should have a comprehensive consideration, although according to the change should be slightly increased, but not frequently capricious.
